How to Get Rid of Scale Bug

pm1878efc added on June 1, 2012 | Answered

I have an infestation of scale on my 2 magnolias, a bay tree and an acer. The bugs appear on the stems and branches and have secreted a white substance which appears like a sticky white cotton wool. I have been blasting them off daily for about a week with high pressure hose, but they return but seem to be less daily. Should I just carry on with my treatment or is there an easier way??
